WELT-BEATING MACHINE.

SPECIFICATION forming part of Letters Patent No. 598,727, dated February8, 18 98.

Application filed April 28, 1896. Serial No. 589,369- (No model.) i

To all whom it may concern:

Be it known that we, ZAOHARY T. FRENCH and WILLIAM G. MEYER, of Boston,county of Suffolk, State of Massachusetts, have invented an Improvementin Welt-Beating Machines, of which the following description,

in connection with the accompanying drawings, is aspecification,-like.letters on the drawings representing like parts.

This invention has for its object to improve the construction ofmachines forbeating out welts of welted boots and shoes; and itconsists, essentially, in the combination of a weltbeating hammer, meansfor operating it, a table upon which the welt is placed, a movablesupport therefor, a movable abutment against which said supportcontinuously rests and which acts to resist the blows of the hammer, atreadle, and a treadle-rodconnecting said treadle with said movableabutment. 7

The movable abutment is constructed and arranged to serve as anadjusting device by which the position of the table relative to thehammer may be varied, and as preferably constructed the said abutmenthas bearings which are at all times directly in the line of thrust ofthe table-support. As herein shown, the table-support is pivoted to theframe, and the abutment is likewise pivoted to the frame, thelatterconsisting, essentially, of a cam of varying radius, so that as it isturned on its pivot it will vary the position of the tablesupport whichrests upon it.

Figure 1 shows in side elevation a weltbeating machine embodying thisinvention; Fig. 2, an end view of the machine, the weltbeating hammerand welt-support or table being omitted; and Fig. 3, a plan view of thewelt-support or table.

The welt-beating hammer a is secured to the lower end of a rod or bar a,having its hearings in projecting portions a a of the main framework A,said rod or bar a being movable vertically in its bearings. A sleeve 19is placed upon or embraces the rod or bar a at a point more or lessmidway its length, it having a laterally-projecting stud b, and a mainrotating shaft 0, having its bearings in the main frame A, has securedto it 'suit-' able driving-pulleys at one endand has projecting from itsopposite end a crank-pin c, and a link 19 connects'said crank-pine withthe laterally-projecting stud b on the sleeve 12, so that as the shaft 0is rotated the sleeve 12 will be reciprocated. l

' In order that the reciprocating sleeve may "impart a correspondingmovementto the rod orba'ra, we have secured to said rod or bar at apoint just above the sleeve b a collar cl, against the lower end ofwhich said sleeve 79 bears, and a strong spiral spring cl encircles saidrod or bar a, the upper end of-which bears upon or against the sleeve 19and the lower end of which bears upon or against adj usting-nuts dturned on a threaded portion of said rod or bar. As the shaft 0 rotatesthe sleeve b,'acting'upon the spring cl, depresses the welt-beatinghammer,and then acting upon the fixed collar d raises said weltbeatinghammer.

By connecting the rod or bar a with th means for operating it by meansof the loose sleeve 6, fixed collar d, spring cl, and adj usting-nuts dit will be seen that an adj ustable yielding connection is providedwhereby the welt-beating hammer will deliver a succession of yieldingblows.

6 represents the table upon which the welt to be beaten out rests, andit is herein shown as having a tapering lip adapted to enter the creaseor inseam or bear against the last at i the face side of the welt.

The table 6 isplaced upon or held by a supportc, pivoted at e to themain framework. The table-support e is formed with a recess for thetable e, the top of the recess being provided with a tongue and the topof the inner end portion of the table being provided with a groove toreceive said tongue, and a set-screw e is provided, which may be used tohold the table 6 fixed in any desired adjusted position, or the table 6may be made movable in and out for a short distance, if

desired, in which case the set-screw 6 will 5 be loosened or omitted anda spring or (see dottedlines, Fig. 1) will be provided, hear ing againsta pin n on the table-support e and againstthe table a, the action ofwhich is to move the table out, and pins n pass up through webs orprojections on the tablesupport and enter slots or grooves formed in theunder side of the table, said slots or grooves being of such length asto limit the forward movement of the table, its rearward movement beinglimited by the inner end of the table bottoming in the recess. The table6, thus yieldingly supported, may be moved in and out in order that thewelt-beatin g hammer may act upon the welt more or less distant from theedge.

It is obvious that the table e may be made integral with the support 6;but by making it separate it may be adjusted in and out or caused toyield.

The pivoted table-support e rests upon or against a cam f, which servesas an abutment for it, and said cam f is pivoted to the frame atf. Thecam f, which thus serves as an abutment for thetable, has its curvedsurface made of gradually-increasing radius from end to end, so thatwhen the cam is in one position, as represented by dotted lines, Fig. 1,its point of shortest radius is in contact or engagement with thetable-support, and consequently the table 6 is more or less removed fromits normal elevated position, and when the cam f is moved into itsopposite extreme position, as represented by full lines, Fig. 1, itspoint of longest radius is in contact or engagement with thetable-support, and as a consequence the table 6 is held in its mostelevated position. By holding the cam f at different intermediate pointsor positions the normal elevated position of the table a may be varied.

As a simple way of limiting the movement of the cam f in onedirectionrl. 6., in a direction to raise the table ean adjusting-screw 0f passes through a projection f on the cam and is adapted to strikeagainst a fixed point or stop f on the frame. The cam has attached to ita treadle rod or chain g, which may be connected with any suitabletreadle for the purpose of depressing it or moving it in a direction tolift the table, and a strong spring g is attached at one end to the camf and at the other end to the table-support, which acts to move the camfin the opposite direction.

This construction of adjusting and operating device for adjusting andoperating the table 6 may be changed in many ways without departing fromthe spirit and scope of the invention, but the particular constructionshownviz., the cam fenables the table to be adjusted and held indifferent planes or elevations and also to be freely moved to facilitateadmitting the work and also provides a good and efficient abutment tooppose or resist the force of the welt-beating hammer.

The table-support 6 has a tendency to turn on its pivot when its table 6is receiving upon it the repeated blows of the hammer, and said supportbears against the cam f continuously, the thrust being in a directiontoward the pivots or bearings f of said cam, such direc tion of thrustcontinuing notwithstanding movements of the cam f to vary the positionof the table.

The front end of the table is made as a stationary nose but it isobvious that a loose roll may be provided without departing from thespirit and scope of the invention.
